During 2019, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific and Indian Oceans. During the year,a total of 142 systems formed, with 100 of these developing further and being named by the responsible warning centre. The strongest tropical cyclone of the year was Typhoon Halong, with a minimum barometric pressure of 905 hPa (26.72 inHg ). Cyclone Idai became the deadliest tropical cyclone of the year, after killing at least 1,303 people in Mozambique, Malawi, Zimbabwe, and Madagascar. The costliest tropical cyclone of the year was Typhoon Hagibis, which caused more than $15 billion in damage after striking Japan.
Similar to the previous year, 2019 was above average in terms of the number of storms. The most active basin of the year was the Western Pacific, which documented 29 named systems. The Eastern Pacific had an average season, although many of the storms were rather weak and short-lived, therefore the number of hurricanes was the least since 2010. The North Atlantic hurricane season experienced an above average number of tropical storms, numbering 18, though most were rather weak and short-lived, especially late in the season. In the North Indian Ocean basin it was extremely active, breaking many records. This included Cyclone Kyarr, the second-strongest Arabian Sea Cyclone on record and one of the strongest cyclone ever in the North Indian Ocean. Activity across the southern hemisphere's three basins – South-West Indian, Australian, and South Pacific – was fairly significant, with the regions recording 25 named storms altogether, with the most intense Southern Hemisphere cyclone of the year, Cyclone Ambali from the Southwest Indian Ocean basin peaking with a central pressure of 930 hPa (27.46 inHg ). Eight Category 5 tropical cyclones formed in 2019. The accumulated cyclone energy (ACE) index for the 2019 (seven basins combined), as calculated by Colorado State University (CSU) was 854.8 units.
The El Niño from the previous year continued into the start of 2019, albeit in borderline-neutral conditions, though many agencies were still predicting it to continue into Spring. [1] [2] This weak El Niño state persisted through Summer, [3] however sea surface temperatures in the Pacific transitioned to a neutral state by August, marking the end of the El Niño and the beginning of ENSO-neutral conditions. [4] [5] These neutral conditions continued in Winter, and onto the next year. [6]
The North Atlantic Ocean experienced their fourth-most active season on record, tied with 1969, at 18 named storms. Most of the storms were weak and short-lived, possibly because of moderately high wind shear that persisted throughout the season. Sea surface temperatures, however, were quite high for tropical cyclone development. Saharan dust counts were fairly sedate throughout the month of September. Andrea, Melissa, and Rebekah were the only storms to become subtropical storms throughout some portion of their lives (Andrea and Rebekah were subtropical for their whole lives). The North Atlantic basin featured a record fifth consecutive year for tropical or subtropical development before the month of June, which the record continues when Tropical Storms Arthur and Bertha form on May 16 and 27, 2020, yet marking the sixth year of tropical development before the season actually starts. The season also featured more than one Category 5 Hurricane, making it one of only seven seasons to accomplish such a feat. [7] Hurricane Dorian was the strongest tropical cyclone for the basin in 2019. Dorian peaked with a strength of 185 miles per hour, and peaked at an intensity of 910 hPa/mbar. [8] Dorian is the record-tying strongest landfalling Atlantic hurricane. The record is tied with the Great 1935 Labor Day hurricane. The accumulated cyclone energy (ACE) index value for the individual basin is 132 units, which is only dubbed "above normal", despite the high count of named storms of 18.
The Eastern portions of the Pacific Ocean was only moderately active, likely because of a weakening El Niño trend that started in late July. The 2019 Pacific hurricane season featured 21 tropical depressions, 19 named storms, 7 hurricanes, and 4 major hurricanes. The first tropical depression didn't form until June 25; which is the latest start on record, since reliable records were kept in 1971, that a first tropical cyclone ever formed. Alvin, the first tropical storm of the season, did eventually become the first hurricane of the 2019 Pacific hurricane season. Barbara, the strongest hurricane of the basin in 2019, was short-lived. However, Barbara did eventually undergo rapid intensification and peaked as a high end Category 4 hurricane on the modern-day Saffir–Simpson Hurricane Wind Scale. Barbara encountered large portions of wind shear and weakened very rapidly. Barbara's remnants did eventually reach Hawaii, but little to no damage was reported. No hurricanes formed in August. It wasn't until September 1 that the next hurricane formed; Juliette; a high-end Category 3 major hurricane. Tropical Storm Akoni was the first storm of the Central Pacific, as well as the second time the name has been used; the first usage was in 1982. Hurricane Kiko was the longest-lived Pacific hurricane of 2019 that tracked mostly over open waters. Lorena was the most serious hurricane of the season, but minor damage was reported. Tropical Storm Narda did make small impacts in Mexico, but they weren't too serious. Tropical Storm Ema was the second and last storm of the Central Pacific. Tropical Depression Twenty-One-E concluded the season when it dissipated on November 17. The total ACE in the basin is 97.9875 units, which is considered "near normal".
The Western Pacific typhoon region was fairly above average. It was the costliest Pacific typhoon season on record, breaking the record set by the previous year. The 2019 Pacific typhoon season featured 51 tropical depressions, 29 tropical storms, 17 typhoons, and 5 (unofficial) super typhoons, with 4 attaining Category 5 status. Typhoon Wutip was a rare February Category 5 super typhoon. No other storms strengthened to typhoons until Typhoon Francisco formed in early August. Typhoon Lekima followed it, which later caused extensive damage in South China. Many more tropical storms and typhoons followed. Typhoon Hagibis was the costliest typhoon of the season and on record, inflicting US$15 billion after making landfall on Japan as a Category 1 typhoon. (unadjusted for 2020 inflation). Typhoon Halong became the most intense storm of the season, as well as the most intense of the whole year, peaking at 905 hPa. Typhoons Kammuri and Phanfone wreaked major havoc in the Philippines in December 2019; Kammuri with its Category 4 landfall, and Phanfone with its high death toll as a prolonged Category 2 typhoon. The accumulated cyclone energy (ACE) index of this season amounted to 269 units, which is considered "near normal".
The season was the most active North Indian Ocean cyclone season ever recorded in terms of cyclonic storms, though the 1992 season saw more tropical storms according to the Joint Typhoon Warning Center. The season featured 12 depressions, 11 deep depressions, 8 cyclonic storms, a record 6 severe cyclonic storms, a record 6 very severe cyclonic storms, a record 3 extremely severe cyclonic storms, and 1 super cyclonic storm, Kyarr, the first since Cyclone Gonu in 2007. Additionally, it was also the third-costliest season recorded in the North Indian Ocean, only behind the 2020 and 2008 seasons.
Amid a weak El Niño event, the season's first named storm, Pabuk, entered the basin on January 4, becoming the earliest-forming cyclonic storm of the North Indian Ocean on record, tying with the 2014 season. The second cyclonic storm of the season, Fani, formed on April 26. Fani became an extremely severe cyclonic storm on April 30, reaching the equivalent of Category 5 status on the Saffir–Simpson scale, then made landfall in India killing 89 people between Odisha and Bangladesh; Fani caused $8.1 billion in damage.
In early June, a strong pulse of the Madden–Julian oscillation (MJO) led to the development of the third cyclonic storm, Vayu, which formed June 10 in the Arabian Sea near the Maldives. The storm subsequently intensified into a very severe cyclonic storm on June 12, after moving northwestward towards northwestern India and Pakistan. No tropical cyclones formed in the month of July. Deep Depression BOB 03 formed on August 7 before impacting East India and Bangladesh. In late September, Deep Depression ARB 02 formed near Gujarat and intensified into the fourth cyclonic storm of the season, Hikaa. Cyclonic Storm Kyarr formed on October 24 and three days later became the first super cyclonic storm since Cyclone Gonu in 2007. The sixth cyclonic storm and a record-breaking fifth very severe cyclonic storm, Cyclone Maha, formed on October 30 after Kyarr dissipated on November 1. Soon afterward, on November 6, the remnants of Severe Tropical Storm Matmo crossed the Southeast Asia overland and again consolidated into a depression. It further rapidly intensified into Very Severe Cyclonic Storm Bulbul. Three more Deep Depressions formed in Arabian Sea in quick succession early in the month of December, of which one strengthened into the eighth cyclone of the season, Cyclone Pawan, which made landfall in Somalia on December 6.
The high amount of activity in the Arabian Sea was related to the strongest Indian Ocean Dipole in 60 years, in which the waters are warmer in the western Indian Ocean than the eastern. [9]
Tropical cyclones have been recorded in the North Indian Ocean since 1891. The 2019 season was the first since 1902 that experienced the development of six severe cyclonic storms out of eight cyclonic storms; in 1902, five cyclonic storms formed and four of them became severe cyclonic storms. [10] The season has also produced the most accumulated cyclone energy in this basin on record.
The 2018–19 South-West Indian Ocean cyclone season was the costliest and the most active season ever recorded since reliable records began in 1967. Additionally, it is also the deadliest cyclone season recorded in the South-West Indian Ocean, surpassing the 1891–92 season, in which the 1892 Mauritius cyclone devastated the island of Mauritius. [11] Two moderate tropical storms formed at the start of this year, Desmond and Eketsang. Five more intense tropical cyclones formed during February and March: Funani, Gelena, Haleh, Idai, and Joaninha. [12] [13] In addition, Savannah crossed into the basin from the Australian basin as an intense tropical cyclone in March. Of these storms, all of them but Haleh and Savannah produced impacts on land, with Idai causing at least 1,303 deaths and leaving at least 2,262 people missing, and causing US$2.2 billion in damages in Mozambique, Zimbabwe, Malawi, and Madagascar. The season set a new record of nine intense tropical cyclones, the largest number since the start of reliable satellite coverage in 1967, surpassing the 2006–07 season.
The 2019–20 South-West Indian Ocean cyclone season was a slightly above-average season in tropical cyclone and subtropical cyclone formation west of 90°E. The season officially began on November 15, however, the formation of the first system—Zone of Disturbed Weather 01—occurred on July 22, 2019 (which failed to organize into a tropical depression), well before the official start of the season. This was the earliest start to a season since the 2016–17 season. For the second consecutive year in a row, the first system formed before the official start of the season. Afterwards, three storms formed in the month of December: Tropical Cyclone Belna on December 2, which brought flooding and strong wind to northwestern Madagascar, Very Intense Tropical Cyclone Ambali, which formed a day later and became the first very intense tropical cyclone in the basin since Fantala in 2016, and Tropical Cyclone Calvinia which stalled near Mauritius and brought heavy rain and moderate flooding to the island nation towards the end of the month, crossing into 2020.
The 2018–19 Australian region cyclone season was an average season that saw the formation of 11 tropical cyclones, six of which intensified further to become severe tropical cyclones. The season officially began on November 1, 2018, and concluded on April 30, 2019; however, as evidenced by Tropical Low Liua in September 2018 and Tropical Cyclones Lili and Ann in May 2019, tropical cyclones can form at any time of the year. As such, any system existing between July 1, 2018, and June 30, 2019, would count towards the season total.
This was the first Australian tropical cyclone season since 2014–15 to feature at least six severe tropical cyclones. It was also the third season in a row to begin prior to the official commencement date of November 1, in this instance with the development of Tropical Low Liua on September 26, 2018. The most active month was December 2018, with a total of seven tropical lows existing in the region at some time during the month. The three strongest storms of the season—Veronica, Trevor and Savannah—all developed in March 2019, and together affected all three of the Bureau of Meteorology's Australian sub-regions as severe tropical cyclones. Overall, a total of five tropical cyclones existed within each of the three sub-regions throughout the season, representing an above-average season for both the Eastern Region and the Northern Region, but a below-average season for the Western Region. The season concluded much later than usual, and well after the official ending date of April 30. Two tropical cyclones developed during May—Lili in the eastern Indonesian archipelago and Ann in the Coral Sea—both of which made landfall as tropical lows after weakening from tropical cyclone intensity. At its peak, Ann was a Category 2 tropical cyclone, and was the strongest storm to form in the Australian region during May since Severe Tropical Cyclone Rhonda in 1997. In total, eight systems were named by the BOM during the season, with two named by the BMKG and one by the FMS.
The 2019–20 season was a below average tropical cyclone season for the waters surrounding Australia between longitudes 90°E and 160°E. A total of eight tropical cyclones formed during the season, which represents the region's least active season since the 2016–17 season. Three systems intensified further into severe tropical cyclones, and three systems made landfall within the region at tropical cyclone intensity.
The season had an unusually late start with the first system, Blake, forming in early January, well after the official start of the season. Blake would later make landfall in northwestern Australia and soon degenerate afterwards. At the same time, Claudia, another tropical cyclone, formed. It persisted for two weeks and reached category 3 on the Australian tropical cyclone scale before dissipating west of Australia. Later that month, a tropical low formed and lasted for a week before dissipating in late January without been named. Three other tropical lows formed in late January and early February. One of them dissipated later. Another one of them has been moving in and out of the Australian region. It was designated 06F by the Fiji Meteorological Service. The third one intensified into Cyclone Damien. In late February, 2 new tropical lows formed, and were named Esther and Ferdinand. Esther didn't strengthen much, but Ferdinand went on to become a Category 3 severe tropical cyclone, equivalent to a Category 2 Atlantic hurricane.

The 2019–20 season was a slightly above-average season in which tropical cyclones formed within the South Pacific Ocean to the east of 160°E. The season has been near-average in terms of activity, with eight tropical cyclones and four severe tropical cyclones forming during the season.
The season began with the arrival of Tropical Depression 01F on November 22, near the Solomon Islands, which would later become Tropical Cyclone Rita. Rita would then peak as a Category 3 on the Australian scale. Tropical Disturbance 02F was designated sometime later, but didn't last long after that. Sarai formed on December 23, lasting into the new year before finally ceasing to exist on January 2. Not too long after that, Tino formed and affected eastern Fiji and the surrounding area before dissipating. On January 24, a depression formed and dissipated the next day without been named. In early February, another low originally in the Australian region crossed the 160th meridian east and emerged in the South Pacific. It strengthened into severe tropical cyclone Uesi and affected New Caledonia and New Zealand. In mid-February four disturbances formed, 07F, 08F, 09F and 10F. 07F & 08F dissipated before becoming tropical depressions but the other 2 strengthened into tropical cyclones Vicky and Wasi. In mid March, Gretel entered the basin. It dissipated shortly afterwards. In early April, Harold also entered the basin from the Australian region. It rapidly intensified into a Category 5 Severe tropical cyclone as it impacted Vanuatu.
There are two systems that formed during this year, Iba and Jaguar. Iba was the first tropical storm to develop in the basin since Anita in 2010, as well as the first fully tropical system to be named from the Brazilian naming list, [14] while Jaguar was a subtropical storm that failed to develop.
Two medicanes formed in this year, Scott and Trudy (Detlef).
The month of January was inactive, with only six tropical cyclones forming, of which three were named. Tropical Storm Pabuk [15] was the earliest-forming tropical storm of the western Pacific Ocean on record, breaking the previous record held by Typhoon Alice in 1979. Pabuk killed 10 people in Vietnam, Thailand and Malaysia, causing $151 million (US$2019) in damage. [16] Moderate Tropical Storm Eketsang killed 27 people in Madagascar in late-January.

Ten tropical cyclones formed in the month of March, including six named tropical cyclones. A total of five systems strengthened into the equivalent of at least a Category 3 major hurricane on the Saffir Simpson hurricane wind scale (SSHWS)—the first such occurrence since September 2018. The month featured Cyclone Idai, which is currently the deadliest tropical cyclone of the year, responsible for 1,007 deaths in southern Africa. [20] Idai was also the costliest cyclone in the South-West Indian Ocean basin, inflicting more than $2 billion (USD) in damages. [21] Tropical Storm Iba became the first tropical cyclone to develop in the South Atlantic since Anita in 2010.

April was an inactive month with six cyclones forming, of which four were named. Cyclone Kenneth became the most intense tropical cyclone to make landfall in Mozambique on record. [24] Kenneth killed 48 people, of which 41 were killed in the country of Mozambique. [25] Cyclone Fani struck parts of India and Bangladesh, killing 72 people in Odisha, [26] 17 people in Bangladesh, [27] and 8 in Uttar Pradesh. [28]

May was a relatively inactive month with eight tropical cyclones forming. Four of these tropical cyclones reached the required intensity threshold to receive official names. Cyclone Lili developed at the beginning of the Australian region off-season, and struck East Timor and Indonesia's Maluku Islands, with rainfall-induced flooding causing minor damage to infrastructure and residential property. Cyclone Ann, another off-season Australian system, developed into a strong tropical storm on the SSHWS, and made landfall in Far North Queensland as a tropical low. Ann was the strongest Australian cyclone to develop in May since Rhonda in 1997. A subtropical storm named Jaguar formed in the South Atlantic, marking the second South Atlantic cyclone of the year, the first time two have occurred in the same year since 2016. The formation of the short-lived Subtropical Storm Andrea to the southwest of Bermuda began the Atlantic hurricane season early for the fifth year in a row.

June was an inactive month in terms of the number of tropical cyclones formed, with only four systems occurring in total. June 1 also marked the official commencement of the Atlantic hurricane season. After the year's longest period without any cyclone activity, the first system in the Arabian Sea for the 2019 North Indian Ocean cyclone season formed on June 10. Named Vayu, the system intensified into a high-end very severe cyclonic storm on the Indian scale, equivalent to a minimal Category 3 major hurricane on the SSHWS. Late in the month, Hurricane Alvin became the first tropical cyclone of the Eastern Pacific hurricane season, marking the latest start to the season since reliable records began in 1971. A tropical depression briefly reached tropical storm intensity near Japan on June 27, and was named Sepat. The cyclone was the first tropical storm to form in the western Pacific in four months.

The month of July was the third most active month in terms of total tropical cyclones and in terms of named storms in the year, with thirteen tropical cyclones forming, of which nine were named, behind August. Among these storms, Hurricane Barry made landfall between Midwestern United States and Southeastern United States as tropical storm, causing US$500 million in damages and one person was indirectly killed by the storm.
